Cartography of a Network Data Model

Cartography of a Network Data Model

By using attributes encoded in the network data model, such as road type, each segment can be displayed to reflect its importance. For instance, the above cartographic representation of a network data model displays three road classes (highway, main street, and street) differently. Descriptive labels for the most important elements and directional signs for one-ways have also been added. To enrich the cartographic message, additional layers of information have been added, namely landmarks. Nodal attributes can also have a cartographic utility, such as displaying if an intersection has traffic lights.
